Premium SSD v1 disks that would cost less on v2
A disk on an older storage tier
Why it happens
The newer tier lets you pay for size and speed separately. Most older disks end up cheaper on it for the same performance.
Premium SSD v2 decouples capacity from performance, so a v1 disk sized up purely to reach an IOPS tier is usually cheaper on v2 at the same real performance.

Applies to microsoft.compute/disksWhat the agent does about it
A Premium SSD v1 disk where a Premium SSD v2 of the same performance costs less.
It will not fix this one
It reports this and takes no action. A check only earns the right to change something once the action behind it can re-read live state before it fires and knows the way back.
